To all whom, t may concern:

Be it known that I, CHARLES E. WHITE, a citizen of the United States,residing at the city of Philadelphia, in the county of Philadelphia andState of Pennsylvania, have invented certain new and useful Improvementsin Hydrocarbon Incandescent Lamps, ofv which the following is aspecification.

Objects of the invention are to provide a lo comparatively simple,efficient, and inexpensive hydrocarbon-lam p for heating Welsbachl andother incandescent mantles, to prevent impurities in the uid fuel or oilfrom interfering with the operation ofv the lamp, and to I5 insure asupply of air for the burner. V

'll/Iy invention consists of the improvements hereinafter described andclaime The nature, characteristic features, and Scope of my inventionwill be morefully unzo derstood from the following description,taken inconnection With the accompanying drawings, forming part hereof, and inWhich- Figure 1 is an elevational View, partly in section, of a lampembodying features of my invention. Fig. 2 is a' sectional 4vievv drawnto an enlarged scale in order to illustrate means embodying features ofmy inventionand adapted to arrest impurities; Fig. 3 is a sectional viewtaken on the line 2 2 of Fig. 2,

3o and Fig. 4 is an elevational view illustrating a modification of theinvention.

In the drawings, 1 is a fount or reservoir Which may be provided With anoil-inlet, as 2. From this reservoir or fount depends an oilsupply pipe3. As shown in the drawings, this pipe 3 extends transversely throughthe fount or reservoir 1 and is provided with a hook or other suspensiondevice 4 and with oil-inlets, as 5. This construction is simple,

4o inexpensive, and ecient.

6 is a needle-valve for controlling the supply of oil.

Above the burner 7 the supply-pipe 3 is arranged so as to receive heat.As shown in Fig. 1, this is accomplished by an offset, as 3, and, asshown in Fig. 4, it is accomplished by a lateral bend or coil, as at 9.The mixingtube 10 supplies the burners 7, of which there may be anyappropriate number, and extends 5o upward, so as to receive vapor fromthe discharge end of the supply-pipe 3. At the discharge endA of thepipe 3 there is a trap 11 for arresting impurities.

As shown in Fig. 2,

this` trap comprises a coupling l2, provided With a vapor-nozzle 13 andinto the interior of which is fitted a cap 14, projecting back into thepipe 3 and provided With vapor-inlets 15, so that impurities traversingthe supply-pipe 3 will fall into the trap 11, While the vapors Will passthrough the openings 15 into the interior of the cap 14 and from thenceby Way of the nozzle 13.

The coupling 12 is provided With a spider 16 (see Fig. 3) and With aVsocket 17, constructed for attachment to the pipe l0. By thisconstruction a passage to the mixing-tube 10 is provided for air and atthe same time means are afforded for suspending the burner or burnersand the pipe l0 from the supply-pipe 3.

In the side Wall is exposed to considerable heat.

Its function is to deflect hot air and cause the same to enter the'openupper end of the socket 17, thus insuring a sufficient supply of airthrough the mixing-tube 10 to the burner or burners.

` In use duid fuel or oil, as gasolene, from the tank 1 passes by theopenings into the supply-pipe 3 and in regulated quantities past theneedle-valve 6 over the top of the burner,

as at 8 or 9, Where it is vaporized. ties collect in the trap 11, fromWhich they Impurimay be subsequently removed, and the vapor traversesthe openings 15 in the cap 14, and from the latter it escapes as a jetor stream through the nozzle 13. The jet or stream of vapor enters themixing-tube 10 along with a 9 supply of air that is drawn or forcedthrough the open upper end of the socket 17 in part by the action of thejet and in part by the aircurrentspwhich are set up beneath the solidcap 19.

This mixture of air and vapor after roo traversing the tube 10 reachesthe burner or burners and is there consumed in order to heat the mantlesor incan'descents.

It will be obvious to those skilled in the art to which my inventionappertains that modiications may be made in details without departingfrom the spirit thereof. Hence I do not limit myself to the preciseconstruction and arrangement of parts hereinabove set forth, andillustrated in the accompanying drawings; but,

Having thus described the nature and objects of my invention, what Iclaim as new,

and desire to secure by Letters Patent, is

l. A hydrocarbon incandescent lamp comprising a supply-pipe providedwith a needlevalve and depending from a fount, a coupling applied to theend of said pipe, a spider attached to and depending from the couplingand provided with a socket, and an air-mixing tube depending from thesocket and provided with a burner, substantially as described.

2. A hydrocarbon incandescent lamp coinprising a fount or reservoir, asupply-pipe eX- tending from the same and provided with inlets and witha needle-valve, a nozzle at the end of said pipe, a coupling connectedwith said pipe, a spider connected with and depending from the couplingand provided with a socket, and an air-mixing tube carried by the socketand provided with a burner, substantially as described.

3. In a hydrocarbon-lamp the combination of a supply-pipe in which oilis vaporized, a coupling attached to the end of said pipe and providedwith an internal receptacle terminating in a nozzle, a cap removablyfitted in said receptacle and over said nozzle and eX- tended into saidpipe and perforated near its top, a spider connected With said couplingand provided with a socket, and a mixingtube attached to the socket,substantially as described.

4. In a hydrocarbon-lamp the combination of a burner havin g anair-mixin g tube extending upward and provided at its upper end with anopening for the inlet of air, and a deflector constructed to preventpassage through it of air and located above and eX- tending over theburner and above the airinlet opening, substantially as described.

5. In a hydrocarbon-lamp the combination of an imperforate detlector, aburner located beneath the same and provided with an upwardly-extendingair-tube open at the top and constructed to receive currents of air setin motion by the ascending currents of gases from the burner,substantially as described.

In ltestimony whereof I have hereunto signed my naine.
